Hi Madan Kumar
It looks like you're on the right track with using the m_map toolbox for polar stereographic projection. However, the code you provided seems to use m_elev and m_coast, which are for elevation data and coastline plotting, respectively, and may not apply directly to your data.
To contour plot your ut, lat, and z data correctly in a polar stereographic projection, try modifying your approach as shown in the sample code snippet below:
load('poldata.mat')
% Polar stereographic projection using m_map
m_proj('stereographic', 'lat', 90, 'long', 0, 'radius', 30); % Stereographic projection, centered at north pole
% Convert latitudes and UT into a meshgrid
[Lat, UT] = meshgrid(lat, ut);
% Plot the contour using m_contourf for filled contours
m_contourf(UT, Lat, z, 'LineStyle', 'none');
% Optional: Add a coastline (this might not be needed for your plot)
m_coast('line', 'color', 'k');
% Add grid lines and labels
m_grid('xtick', 12, 'tickdir', 'in', 'ytick', [60:10:90], 'linestyle', '-');
% Add colorbar for reference
colorbar;
Hope this helps!
